The Kulspruta m/39 (ksp m/39) is a Swedish development of the Browning M1917 machine gun. It is an air-cooled variant of the Kulspruta m/36. While primarily mounted on vehicles, it could also be used as an anti-aircraft weapon, with the latter mainly being chambered in 8mm (8 x 63 mm m/32). After World War II, the 6.5 models were adapted to fire the 6.5x55 m/41 cartridge (6,5mm sk ptr m/94 prj m/41). In the 1970s the machine guns were converted to 7.62×51mm NATO. Ksp M/39s were still in use on the Stridsvagn 122 and Combat Vehicle 90, but were later replaced with more modern machine guns.
